I think it might be difficult to get everyone over here if the old forum doesn't eventually shut down.
Kinda like the coin dollar. It'll never take if they keep the paper dollar bill.
But I like it though, seems to load alot quicker!

The old forums will eventually ride off into the sunset... or get blown up with a few .50 cal shots...
As for a timeframe, as soon as the forums are tested more stressfully and hold up while we (ok, while I) fix issues, then they will be alone.
Just for the record, I wrote them from scratch due to UBB being quite a system hog. (Disk space, memory, and CPU!) These should run ALOT faster, more scalable, and carry increased functionality. Not to mention I am a slave to them now... and Ed will utilize that...
